Can't build this kernel on Arch Linux

[andrea993]

I've downloaded this repository with git clone and next the prebuilt toolchain from https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 Next I've added the ...arm-eabi-4.6/bin on PATH. Then I've tried to build the kernel:

export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-eabi-
make hammerhead_defconfig

Up to here no error

make -j8

The output is here: http://pastebin.com/LVZ4huyB It seems to have ended without errors but there is not a zimage in arch/arm/boot/ where is the kernel?

[andrearch@archlinux ElementalX-N5]$ ls arch/arm/boot
bootp  compressed  dts  install.sh  Makefile

Thanks

Try arm-eabi-4.8. My bet is this kernel only builds with 4.8 or above. 4.6 was never used to build a kernel on hammerhead. Google started with 4.7 back in KitKat days for this device. 4.6 hasn't been used since Android Jellybean.

I've tried with 4.8, it does the same. But how can I detect where the compiled kernel files was sotored?

Location of compiled kernel is arch/arm/boot/zImage-dtb all intermediates to that are stored as *.o files.

BTW, you are using the incorrect defconfig. The defconfig name is elementalx_defconfig not hammerhead_defconfig. If it doesn't build correctly with 4.8 you'll have to try the aosp arm-linux-androideabi-4.9 since there is no arm-eabi-4.9 or you could try a custom 4.9 toolchain like https://bitbucket.org/UBERTC/arm-eabi-4.9 for example.

Also you'll probably need https://github.com/UBERMALLOW/kernel_lge_hammerhead/commit/337c6f28ce9a677260c690509fa23c89f610b108 to overcome your perl error which seems to be part of your compile issue as well.

Editing the perl script it works. Can someone correct the code? Thanks

@andrea993 If I were you I'd pull request the change that way it would take @flar2 only a second to merge. Otherwise it will take him more time and he'll be less likely to do it. Just my thoughts on the matter.

Ok I will do the request. You are right!
